Mercury is 5.8 × 10^7 km from the sun. Neptune is 4.5 × 10^10 km from the sun. How much further is Neptune from the sun than Mercury?

To find out how much further Neptune is from the sun than Mercury, we need to calculate the difference between their distances from the sun.

The distance of Mercury from the sun is 5.8 × 10^7 km.
The distance of Neptune from the sun is 4.5 × 10^10 km.

To calculate the difference, we subtract the distance of Mercury from the distance of Neptune:

4.5 × 10^10 km - 5.8 × 10^7 km = 45000000000 km - 58000000 km = 4.4984 × 10^10 km - 0.058 × 10^10 km = 4.498342 × 10^10 km.

Therefore, Neptune is approximately 4.5 × 10^10 km further from the sun than Mercury.
